RV'ing, and especially fulltime RV'ing, is all about compromises. Most of these fall into the categories of need/convenience, space availability, and weight, (not to mention cost). An air compressor really can fall into all of these. Each of us has differing requirements, so what works for one may not work for others. For instance, I prefer not to wait 5 to 10 minutes to get 5psi @ 125psi, so I have a 150psi Porter Cable pancake, that weighs about 25-30 lbs. While shopping for a compressor, I did see others I liked better, but most were too heavy for my preference, so I "compromised".
Having a compressor that weighs 30lbs, rather than 83lbs, just means I can load on more stuff the DW has a "need" for!!
Of course, I do have an onboard Onan generator, at about 290 lbs, that can take care of my need for 120V, for the compressor! (Now that is what I call compromise, and weight management!!)
